Hello!
I have x51v with WM5.0 (ROM ver. A12). I use 4GB CF storage card and recently noticed my device shows > 2GB files as empty files and can't read them. These files can be deleted and in use/free space indicator shows right figures.

Is it a confirmed OS-related limit? Can it be patched?

IDK, what files are over 2gb, movies?

If they are you should be able to get them under 2gb easily.

Yes. I've been using my card for a while and first time I've noticed that limit it was a movie.

Re-compressing and stripping additional audio channels every time i get an big avi is inconvenient. It can be done, but in case it can be avoided, I'd better avoid it.

I believe that 2GB files is a limitation of the FAT filesystem. Most people don't notice it on desktop computers these days as NTFS is practically the standard for new windows systems but the limitation is present on all FAT filesystems.

More recent developments in paper-based technology include improved ‘write-once’ update devices which use tiny rolling heads similar to mouse balls to deposit colored pigment.

Provided file exeeds filesystem limit, one even hasn't an ability to write it to disk.

Check wikipedia for details: fat16 has limit of 2Gb and fat32 has limit of 4Gb.
Filesystem on card is fat32 and thus my file doesn't exeed any limits.
